Abstract

Techniques described herein use waveform signaling for conserving user equipment, UE, resources. An exemplary method executed by a first UE includes receiving a first indication of a first waveform, of a plurality of waveforms, to be used for one or more downlink communications associated with the first UE, receiving a second indication of a second waveform, of the plurality of waveforms, associated with downlink communications of a second UE, receiving the one or more downlink communications using the first waveform and processing the one or more downlink communications based at least in part on the second indication of the second waveform. A corresponding base station generates a first transmission layer of a multi-layer communication using a first waveform of a plurality of waveforms, generates a second transmission layer of the multi-layer communication using a second waveform of the plurality of waveforms, wherein the first waveform and the second waveform are different, and transmits the first transmission layer and the second transmission layer using a same time resource and a same frequency resource, wherein the first transmission layer is transmitted using the first waveform and the second transmission layer is transmitted using the second waveform.
